Website for the proofs of trig derivatives.. http://math2.org/math/derivatives/more/trig.htm I just stick to them as rules that I follow, http://en.wikipedia.org/wiki/Differentiation_rules#Derivatives_of_trigonometric_functions

You can find derivatives of trigonometric functions by using first principal [And basic trigonometric identities] or chain rules for more complicated trig. functions.

Do you know the first principal of derivative calculation?
